Flex clamp in a disc drive for retaining a voice coil motor magnetic pole on a base

A disc drive includes an actuator assembly mounted on a base. The actuator assembly is able to move a transducer head over a data surface of a disc. The disc drive also includes a voice coil motor that is able to rotate the actuator assembly. The voice coil motor includes a bottom pole adjacent the base, an opposing top pole adjacent the cover and a coil mounted on the actuator assembly between the top and bottom poles. A flexible cable is coupled to the head and has first and second ends and a middle section extending between the first and second ends, wherein the first end is secured to the actuator assembly. The disc drive also includes a flex clamp fastened to the base and securing the second end of the flexible cable to the base. The flex clamp has a body and a clamp arm extending from the body. The clamp arm extends over the bottom pole of the voice coil motor and retains the bottom pole between the clamp arm and the base.
